Not sure precisely what you’re getting at, but Tesla DID invent, or at least had working, radio theory long before Marconi made it famous.
That’s not propaganda, it’s a fact.
I should add... Tesla didn’t die penniless because he made this stuff NOT for profit, he died penniless because he couldn’t seem to get a break, and did try to get contracts on various things from AC motors and generators to radio systems. He demonstrated the first radio-controlled boat (I think it was actually a submarine) in the 1890s.
Technically.... Tesla didn’t “invent” radio either, it was actually a man named Hertz who first was able to produce radio waves.
Tesla took it a step or two further, and Marconi made it ‘practical’ (in his demonstration of transatlantic transmission).
Socialism does not inspire one to innovate. Hard to admit this but sometimes I miss the USSR, with whom at least we had a shining example of how retarded a communist society looks in the real world.
Capitalism brought us Apple Computers and the Windows UI. Enough said.
